(54) SEALING DEVICES SUITABLE FOR USE ON ROOFS AND THE
STRUCTURES SO FORMED
(71) We, KELSEAL LIMITED, a British company of Kelsey House, Wood Lane
End, Hemel Hempstead, Hertfordshire,
HP2 4RQ, do hereby declare the invention, for which we pray that a patent may be granted to us, and the method by which it is to be performed, to be particularly described in and by the following statement:: According to this invention, there is provided a structure including sheet material and supporting bars or fixing members supporting the sheet material or holding the sheet material in position, the structure further including a container, one of the bars or fixing members projecting into the container at one side of the container but not projecting out of the container at the opposite side of the container, so that part of said one of the bars or fixing members lies within the container, and sealant material, in contact with said part, the inside of the container and the sheet material adjacent the bar or fixing member forming a watertight seal between the bar or fixing member and the sheet material.
In the examples shown in the accompanying drawings, there is a wide opening at said one side of the container but no opening at the opposite side of it.
The structure may be a roof, for example, and the sheet material may, for example be corrugated.
There is preferably a layer of at least i inch thick of the sealant material on said part of one of the bars or fixing members and on the sheet material.
The sealant material may be substantially non-setting material or a setting material.
The seal may be made between, on the one hand, a roof-supporting or claddingsupporting bar, for example a glazing bar, or a roof-fixing or cladding-fixing member, for example a bolt, a screw, a rivet or a nut, and, on the other hand, the sheet material which is roofing or cladding material, the container, which has a wide opening at said one side, having, before assembly of said structure, been -filled or only partly filled with the sealant material which does not react with the bar or fixing member nor the roofing or cladding material but adheres to therh and forms a substantially permanent, water-tight weatherproof seal between the bar or fixing member and the roofing or cladding material, the container having been placed on the bar or fixing member so that the latter entered the sealant material in the container and some of the displaced sealant material came into contact with the roofing or cladding material.
The container may be cup-shaped (for example substantially in the form of a tailor's thimble but about twice as large) with an outwardly-turned rim and if desired a hemispherically rounded top, or, alternatively, the container may be trough-shaped, the width of the trough, internally and externally, preferably increasing from its base to its mouth.
In all cases there may have been a layer of paper or other suitable material over a mouth of the container if the container was full or only partly full or over the surface of the- sealant material in the container if the container was only partly full. The layer is removed before the container is used as indicated above.
In all cases the container may be substantially rigid or flexible or, as positioned facing the sheet material, it may be substantially rigid remote from said sheet material and flexible adjacent said sheet material. The container may be made of readily deformable and resilient material, which in these respects may be similar to rubber, and may be moulded from ethylene or propylene polymer or a material having as its major ingredient an ethylene-propylene copolymer or a butyl rubber. Then the operative can locate the container in the appropriate position and then exert pressure manually to force the sealant material to be displaced to where it is needed, for example to form a ring where a nut or the head of a bolt, screw or rivet touches or comes close to the roofing or cladding material, the ring touching a ring-shaped area of each of them.
The container may instead be made of thin sheet metal.
In all cases, the sealant material can be rubber-containing and the rubber may be butyl rubber and whether or not it is butyl rubber the rubber content of the sealant material is preferably at least 1% by weight but preferably it is not more than 10% by weight.
The sealant material is preferably such that it can be deposited in the container in a factory and the container, with the sealant material in it, and others like it, can be packaged in the factory ready for use on site and/or the sealant may be such that it can be deposited in the container, on site, by means of a gun.
Substantially non-skinning, i.e. nonoxidising, properties of the sealant material are highly desirable and it should inhibit rusting or other degrading of the bar or fixing member and roofing or cladding material and should remain pliable substantially indefinitely.
We believe that suitable materials satisfying all these criteria are already sold by us as "rubberised gun sealant or mastic" or "rubber-based sealant or gun mastic" (which has a higher rubber content). A suitable material has substantially the following proportions by weight:
butyl rubber 2%
hydrocarbon oil 22%
wetting agent (for example oleic or
stearic acid O.5% asbestos fibre 6%
so called "whiting", i.e. powdered
chalk 55%
white spirit 14.5% The white spirit is a volatile solvent which is expected to evaporate completely from the sealant after application of the sealant.
The hydrocarbon oil is an oil with high flash point and low volatility which will not evaporate in normal use of the sealant.
A structure in accordance with the invention, and optionally in accordance with any one or any combination of the preferable features (described above) of such a structure, may, for example, be in accordance with either of the following two descriptions
(1) a bolt passes between two pieces of
sheet material and into a bar sup
porting them, the head of the bolt
being in the container and the sealant
material being in contact with both
pieces of sheet material
(2) the container is trough-shaped, the
structure including a bar of T-shaped
cross-section with its stalk passing
between two pieces of sheet material,
which rest on the two parts of the
cross-arm of the T, the stalk of the
T projecting into the container and
the sealant material being partly be
tween the stalk and the pieces of sheet
material.
Examples in accordance with the invention are described below with reference to the accompanying drawings, in which: Figure 1 shows part of a structure according to the invention,
Figure 2 shows the same part in a structure according to the invention,
Figure 3 shows another structure according to the invention, and
Figure 4 shows the structure of Figure 3 and others like it, in a roof.
Figure 1 shows a cup-shaped hollow container 1 moulded from polyethylene and having a hemispherically rounded top 2 and a circular outwardly-turned rim 3 defining a wide opening 4 at its bottom. Sealant material 5 according to the detailed formula given above is in the container but only partly fills it and a layer of paper 6 extends over the surface 7 of the sealant material.
Figure 2 shows part of a roof including flat sheet material 8 (for example steel, asbestos, glass or synthetic translucent material) held on a steel bar 9 of L-shaped cross-section by means of a hexagon-headed steel screw 10 which paasses through a washer 11, the roof being such and being so positioned that there is a tendency for water to fall or form on the sheet material 8 and pass downwardly over it to the location of the washer and the screw, where it will tend to damage both of them and the sheet material in time and perhaps eventually create and pass through gaps.This is countered by simply placing over the screw head and over the washer the part according to Figure 1, after the removal of the paper, so that part of the screw head enters the container 1 and the sealant material 5 is displaced as shown and, whilst still in contact with the inside of the container 1, forms a layer at least 9 inch thick, everywhere it contacts the washer and the screw head and the sheet material 8 adjacent the washer and the screw head, so that it provides a seal between the screw and the washer, on the one hand, and the sheet material on the other hand. Seals between sheet roofing material and rooffixing bolts, rivets and nuts can be made in the same way, as can seals between sheet cladding material and cladding-fixing screws, bolts, rivets and nuts.
Figure 3 shows the cross-section of a glazing bar 12 of T-shaped cross-section on the flanges of which, i.e. on the cross-arm of the T, are laid the edges of two sheets 13 and 14 of glass which are supported by the glazing bar and are separated by gaps 15 from the web 16 of the glazing bar, i.e. the stalk of the T. A moulded, trough-shaped polyethylene container 17, of which the width, internally and externally, increases progressively from its base to its mouth, and of constant cross-section throughout and completely full of sealant material 8 according to the detailed formula given above, (and with a layer of paper over its surface which is removed before use) is pushed over the top of the web 16 of the glazing bar 12, which enters the container 17 and displaces some of the sealant material into the gaps 15 and more of it out of the container at its two sides.The sealant material forms a layer at least W inch thick everywhere it contacts the glazing bar and the glass and forms a seal between the glass and the glazing bar. In a similar way a seal could be made between a cladding-supporting bar, for example of T-shaped cross-section, and sheet cladding material.
Figure 4 shows a number or arrangements 19 according to Figure 3 spaced apart on a roof 20.
In each case the sealant material does not react with the bar or fixing member nor the roofing or cladding material but will adhere to them and form a substantially permanent, water-tight, weatherproof seal between the bar or fixing member and the roofing or cladding material. In each case sealant material remains in contact with the inside of the container.
